If by "evolution" you mean "biological evolution," and if by that term you mean "changes in which living creatures exist on our planet," that began almost as soon as the first objects that can be considered to have "life" appeared here. The Late Heavy Bombardment of about 3.8 billion years ago would (most likely) have made any life here impossible to continue, but bacteria (a fairly advanced form of life) seems most likely to have been here between about 3.5 and 3.0 billion years ago.
So some point between 3.8 and 3.0 billion years ago.
Give or take a couple weeks.
Evolution begins with self replication. Evolution on Earth began around four billion years ago. We don't have any record of that long lost microscopic beginning, but it may have been a single molecule that could make copies of itself.
No.
